Cancer treatment as a
particular area of concern

Cancer treatment in the US cost more than $90
billion in 2006


Just under 5% of total US spending on medical care
From 1990 to 2008, overall costs of treating
cancer more than tripled in nominal dollars and
more than doubled in inflation-adjusted dollars

cancer
(Schrag D. NEJM. 2004;351:317-319)
Reasons for increasing costs of
cancer treatment

Overall increase in spending for cancer care reflects
increases in both price and quantity of care


Between 1991 and 2002, the proportion of breast cancer patients
receiving chemotherapy and the average cost of the
chemotherapy both roughly doubled. Similar trends have been
observed for other types of cancer.
The increases in price and quantity reflect the introduction
of new medical technology

Newer cancer therapies are more expensive than the prior
standard of care; they also expand the pool of treatment
candidates (e.g., because of broader indications, reduced side
effects).

2010;303:1086-1087.
Pharmaceutical cost increases
also raise concerns

Spending on drugs rose from $40.3 billion in 1990
to $216 billion in 2006 (more than a three-fold
increase in real dollars)

Drug spending about 10 percent of total health care
expenditures but has been growing faster than costs for
physicians’ services or hospital care

What drives increased spending
on pharmaceuticals?

Number of prescriptions dispensed (42%)


Types of prescriptions (34%)


Average prescriptions per capita increased from 7.9
to 12.4 between 1994 and 2006
newer, higher-priced drugs replacing older, lessexpensive drugs
Manufacturer price increases for existing drugs
(25%)

Is increased spending on drugs bad?

Prescription drugs can treat—or prevent—serious
illnesses


But there is considerable over-prescribing—many
people receive





Consider, for example, statins to lower cholesterol and the risk
of heart attacks, insulin to control blood sugar
Prescriptions when they don’t need a drug (e.g.,
methylphenidate)
A brand-name drug when a generic could be taken,
An expensive drug when a less expensive alternative would
work as well (e.g., esomeprazole for heartburn), or
A very costly drug that provides little benefit (? bevacizumab)
Covering very expensive drugs may be done for only
some, and at the same time divert limited funds from
more effective health care, particularly for the poor
Can we afford these drugs?

Bevacizumab (Avastin) (monoclonal antibody to block
blood vessel growth) = $4,000-$9,000/month


Cetuximab (Erbitux) (monoclonal antibody to block cell
growth) = $17,000/month


For treating non-Hodgkin’s lymphoma
SIR-Spheres (radioactive microspheres) = $14,000/dose,
with an overall cost = $150,000?


For treating metastatic colon cancer; also head and neck cancer
Ibritumomab (Zevalin) (monoclonal antibody that binds a
radioactive isotope) = $24,000/month


For treating metastatic colon cancer; also lung and breast cancer
For treating liver metastases from colon cancer
Depends on their benefit—commonly measured in
QALYs
QALYs

QALY = quality adjusted life year
A treatment provides one QALY if it prolongs life for
one additional year in perfect health
 A treatment provides 10 QALYs if it provides 10 extra
years of life in perfect health or if it provides 20 extra
years of life at a quality of life that’s half that of
perfect health
 Allows comparison of treatments for different medical
problems (e.g., hemodialysis and coronary artery bypass
surgery)


Cost-effectiveness can be measured by calculating how much
it costs per QALY of benefit for a particular treatment
When is a treatment cost-effective?

“Expensive” more than $100,000/QALY

NICE rarely accepts above $45,000


“Reasonable” up to $50,000/QALY


NICE may accept up to $45,000
“Very Efficient” less than $25,000/QALY


Steinbrook R, NEJM. 359;19:1977-1981
NICE accepts when no more than $30,000
Most writers use $50-100,000 as upper limit of good
value, but public preferences suggest upper limit over
$250,000

Examining the cost and cost-effectiveness of
adding bevacizumab to chemo in metastatic
colon cancer



Randomized trial compared chemotherapy alone vs.

Bevacizumab regimen prolonged median survival from
15.6 to 20.3 months (p<0.001)
Cost of extra 4.7 months?



$101,500 (assuming $5,000 per month for bevacizumab)
$259,149 per year of life gained (not quality adjusted)
Other studies have found a cost per QALY between $143,000
and $171,000 for bevacizumab

Do oncologists believe bevacizumab
offers good value?




Survey of 139 academic med oncologists at two hospitals in
Boston; 90 responded (65% of sample)
Designed to estimate cost-effectiveness of bevacizumab.
Participants asked: How much of a survival benefit would
be needed to justify a drug that costs $70,000 a year more
than standard therapy? Does bevacizumab offer “good
value” for the money?
Mean implied cost-effectiveness threshold for bevacizumab
was $320,000/QALY (median at $280,000).
Only 25 percent of the oncologists thought bevacizumab
provides a good value—those who thought it did not provide
good value tended to underestimate survival benefit or
overestimate costs


Do patients believe bevacizumab
offers good value?

Study of willingness to pay and consumer value for five
high-cost drugs



Bevacizumab, trastuzumab, rituximab, imatinib-mesylate,
erlotinib
A 25 percent reduction in out-of-pocket costs to patients
increases by 5 percent the likelihood that patients will
initiate treatment
Value to the patients was four times the total cost to
patients and insurers of the drugs. However, the valuecost ratio was lower for the oral drugs (for which cost
sharing is lower and for which the ratio was less than one
for more than half of the patients)

Is it cost-effective to add erlotinib to
gemcitabine in advanced pancreatic
cancer?
Cost effectiveness analysis of erlotinib in
pancreatic cancer
Study enrolled 569 patients and compared
gemcitabine alone versus gemcitabine plus erlotinib
Median survival improved from 6.0 to 6.4 months
Cost of extra 0.4 months?
Erlotinib adds $16,613 retail for six months or
 $498,379 per year of life gained ($332,252 per year of
life gained for a 4 month course of therapy)

Expensive new drugs and the poor

Cost pressures are similar for privately insured and
publicly insured (or uninsured), but the pressures
are accentuated with the poor
Program and personal budgets are tighter
 Trade-offs are more tangible—when a state’s Medicaid
budget rises, spending on other public services (e.g.,
schools) may decline, and this can pit poor against
other taxpayers


of total state spending)

Expensive new drugs and the poor

Difficult to protect the poor when it’s only the
poor whose interests are at stake
Political decisions driven by interest group advocacy,
and the poor often fare poorly in such a system (but
sometimes their interests coincide with those of more
effective advocates—see formulary restrictions)
 Need to link the fortunes of the poor to those of
others (Medicaid versus Medicare) and need other
systemic reforms to address the wasteful spending
problems

Impact of 2010 health care legislation

Health care disparities should be narrowed
because of expanded access to care. However,
 The
maintenance of a multi-tiered system will
preserve a good deal of the disparity between rich
and poor.
 Most
of the newly-insured poor will receive coverage
through Medicaid
 Not
enough done to counteract the incentives for
inefficient spending on health care
 Still
largely maintains the fee-for-service model
Need to reduce over-prescribing

Important social pressures
The identifiable victim versus saving statistical lives (low
osmolar contrast media and the Canadian experience)
 Physician relationships with industry (consulting fees for
opinion leaders)
 Physician reimbursement (more generous reimbursement
leads to more costly regimens for metastatic cancer)
 Patient desire for a prescription (direct-to-consumer
advertising and cyclyooxygenase-2-inhibitors (coxibs) for
arthritis (e.g., rofecoxib))


Counter-regulation is critical (e.g., preferred drug lists,
global budgets), but some regulations cause more
harm than good (e.g., prescription caps)
